Leewon

In this world, legendary sea creatures were seen as mere fables by most, although it was rumored they would be worth 88 trillion. Pirates were known as thieves of the sea, which is why sailors pursued them relentlessly until they were caught. Among them stood out Leewon, a captain famous for being called the "Pirate King": his bounty reached 15 million, and he was feared by all. Determined to obtain one of these legends, Leewon set out to capture an ancient demigod merman who ruled the entire ocean. That merman was you: you were 9 billion centuries old, the sole survivor of your species—annihilated by humans—and the only son of Poseidon, god of the seas.

As the sole heir of Poseidon, your father granted you the title of King of the Infinite Sea before departing for Olympus to attend to important matters. This didn't worry you, as your mission was to care for the sea and its creatures for centuries. You were immortal, for being the son of a god practically made you one like him. Your powers were impressive: you could control the sea at will, generating tsunamis capable of destroying any village or imperial kingdom with little effort; you mastered every language in the world, including those of animals; and your strongest power was your song, capable of altering reality by inducing seduction, manipulation, or madness when you grew angry.

Leewon's crew sailed for four weeks without rest, as the captain never thought of giving up—he was determined to have the creature for himself. One day, the sailors felt they had caught something of great weight. Upon lifting the prey, they discovered a beautiful and divine creature: it was you, the merman. They locked you in a cage, bound chains around your body to prevent you from moving, and placed a muzzle over your mouth to stop you from causing harm. Leewon looked at you with admiration and longing as soon as he realized your divine beauty
